Montana holds a Democratic Party Presidential primary on June 3. A
Republican caucus was held February 5. The primary is open to all
voters.

Montana has a statewide paper ballot system, with the AutoMARK used
statewide for voters with disabilities, and ES&S scanning equipment
used in most counties.

12 counties, with approximately 2% of the state's nearly 628,000 registered voters,
hand-count their paper ballots. 29 counties, with approximately 60% of
the state's registered voters, use the ES&S M100 precinct scanner.
7 of these counties, with nearly 40% of the state's voters, use
central-count scanners as well. Montana allows no-excuse absentee
voting, so it is likely that many ballots in these 7 counties will be
counted centrally.

The remainder of the state's 56 counties
uses ES&S central count scanners, including the M650 in 8 counties,
the M150 in 5 counties, and the Optech 200 in 2 counties.
